VALVE OR CUT-OFF.

Specification of Letters Patent.

Patented Sept. 7, 191.2.

Application filed August 14, 1907, Serial No. 338,546. Renewed December 14, 1911. Serial No. 665,749.

f ARD and GEORGE W. Duinen, citizens ot the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Valves or Cut-Offs, of which the followingy is a specification.

This invention relates to Valves or cntotls of the General type disclosed in our prior patent l o.v 86654110, granted Sept. 17,

1907, wherein means are provided ttor de tnchably lmounting the valve and its seat to permit ,convenient renewal or repairs of these and the coacting parts ot' the vulve without disturbing the valve casing, and also for securing tight joints between the parts of the valve tov elieetually prevent leakage.

Theobject of the present invention is to improve the valve structure referred to and to. provide a construction whereby the parts may' be assembled and disassei'nbled in a more ready and convenient manner, whereby the joint between the bonnet or hond, casing and cap may be adjusted without re leasing the cap, and whereby the valve seat may be easily and quickly withdrawn from the partition by manipulntion of the valve cage.

lvlVith these and other objects in view, the invention consists of the novel features 01"' construction, combination and arrangement oit' parts hereinafter fully described and claimed, reference being` had to the acconxpartying drawings, in which Figure 1 is a central vertical longitudinal section through n, valve or cutoff constructed, in accorduncc with the invention. Fig. is n horizontal section on line 2 2 of Fig. 1. Fig. 3 is a side elevation of the valve cage or barrel. Fig, 4e is. a top plun view ot' the valve. Fig. 5 is a similar view of the valve seat'.

Referring now more particularly to thc drawings, the numeral l designates n valve easing' having` inlet und discharge branches 2 und 3, a partition f1 separating .said branches and toi-ined with n beveled scat receiving opening' i', and an upwurdly extending: iinnge or neck G externally screw thread-ed .find 'provided with an internalv shoulder 7, :L beveled joint tace 8 and dinnietrioully opposite 'vertical M torined 1n its thickened surface below the shoulder and opening'. nt their vupper ends grooves 9' through the same. The neck is arranged above the seat receiving opening; in the partition and its lower portion conforms substantially in dimensions with the aren of the upper enlarged portion of said.A

opening.

A detachable valve seat 10 tits snugly within the receiving` opening' 5 and hes a beveledouter face to tightly engage the beveled wall of the opening'. Said seat is also provided with an upwardly extendingr flange 11 provided with a series of outwardly extending' or radial .segmental lugs 1Q overhnnging the body of the sent to produce interveningV receiving grooves 13 open at their ends for eonnuunicntion with the spaces 14 between the adjacent ends o't' the respective lugs. The valve sont is carried by and. detaehably connected with a or barrel 15, comprising an upper cylindrical body portion 1G adapted to approximately snugly lit within the lower portion of the neck 6 and. provided with a plurality of depending wings or urms 1T'. spaced to provide intervening ports 18, said. arms havin;v a spaced arrangement equivalent to the spaced arrangement of the spaces 1l botween the lugs 12 ot` the vulve sont and bcinfny provided at their lower end with transverse grooves 19 for interlocking engagcuicnt with the lugs. ln applying the vulve scat to the cage or barrel` the pui-ts ure relatively disposed to Seat the lower ends ot the nrins or wings 1T into the spaces 14, and then by imparting a partially rotar \v movement to the scut or canje the lugs 12 will be brought into interlocking ennegrenient with the grooves 1S), the lower shoulders of which will sont within the grooves 13. By reverse rotary movcincnt the seat and enfle inay he disconnected. :is will be readily understood. Dininetricnlly dis-- posed upon the body 16 o` the cugru nre lugs 2O adapted to llt within the grrotwcs 9 to hold the canje against rotation when tilted within the "alve easing', while perlnittii'n: it to have u vcrticnl up und down or .sliding` movement. Ono of these luos 2O und the ooactingr groove 9 are preferably wider than the other lue; and `groove to pei-init the cane to be inserted in av deterl'nined nuiuucr only into the rinsing, whereby it muy ulwalvs' be tittcd in the casing in such iuuuncr neither one ot' tbc zii-nis or win 1, the puth oit the water `flowing' lroui the inlet connection to the port in the valre scat,

with a V-shaped 27 rises y of a wrench and provided in its top with a tit within the opening 28. The upper endV of the bonnet is externally A head 21 providedM to close'the top of the barrel oricage, to occupy the neck 6y above the shoulder 7 vand to cooperate with said shoulder in the manner hereinafterdescribed. This head is formed with a de.

pending flange 22 externally screw threaded 'to engage internal threads on the body 16 -V-shaped recess. A cap nut 24 is employed to close the neck and conne the parts of the valve mechanism in position,,said cap being provided with a depending internally threaded Harige 25 to engage the neck and having its body portion extending inwardly to overlie the-head 21 and formed or triangular annular joint flange 26 to tit into the aforesaid V-shaped recess and effect a tight closure of the joint between the neck and head to effectually prevent liabilitv of the escape of fluid from the casing through the neck. A dome portion from the body of the cap and is eX- ternally of angular form for the application circular opening 28. i

The head 21 is integral with the lower end of and forms a part of a bonnet 29 which extends upwardly through the cap and is formed with an annular liange 30,to snugly screw threaded to receive a gland nut 31 adjustably confining therein suitable packing 32. Below' said threaded portion and above the ange 30 the bonnet is formed with an angular surface 33 for the application of a wrench.

A valve 34 is provided to engage the seat 10 and control the port thereof aiid'is de tachably connected with the lower end of' a stem 35, said valve being beveled to seat upon the beveled riin edge of the flange 11. As shown in Fig. 4, the valve is formed upon its upper surface 'with a substantially U- shaped boss 36 having a groove 37 comniunieating with the socket or space 38 bounded thereby, said groove and socket being adaptcd to receive a head 39 formed upon the valve stem and the lower portion of said stem, as indicated in Fig. 1, bywhich the stein is swiveled to the valve. This construction also provides a connection by which the valve may be slipped onto and oft' the stem by a lateral or radial movement,

`thus lpermitting of the ready renewal of an ld..v'alve and application of anew one, as-

will4 be easily understood. The stem is Iformed with a thread 40 engaging a correponding thread on the head and base of the bonnet through which the stem passes, the stem also extending upwardly through the packing 32 and glandnut 31 and being provided at its upper end with an operating head,

handle 41 clamped in position thereon by a nut 42. I

Inv the operation of assembling the parte, the stem is first applied to the bonnet and the valve is next fitted upon the lower end of the stem andthe barrel or cage engaged with t-he threaded flange 22, after which the valve seat is connected with the cage, the parts thus far described fitted into the valve casing, the cap brought into operalive position and screwed upon the n'eck, and the handle 41 nally applied tothe upper end of the valve stem. When the parts arethus fitted in position the lugs 20 on the cage Y or barrel' are seated in the grooves or recesses 9 bv which the cage is held from rotation butuis fitted to slide vertically, so that, after the cap has been* fully screwed on, upon apf plyng a wrench to the portion 3 3 and turn- .ing the bonnet in a counter-clockwise direction the head 21 will be drawn upward until its seat tace 23 tightly engages the joint flange 26, while at the saine time the valve cage or barrel will be moved downward to force the valve seat 10 tightly into the receiving opening 5. It will thus be understood that by a rotaryl movement of the bonnet to the leftthe valve seat may be firmly applied in position and the head'21 simultaneously adjusted to effect with the cooperating parts 8 and 26 a tight closure between the neck, cap and head.

By the general construction described, it will be understood that the valve and valve seat may be conveniently, disconnected to permit of their removal and the application of a new valve and seat whenever occasion requires in a convenient manner without removingv or in any manner disturbing the valve casing, which may remain applied in the line of piping while repairs are being 'mada -By simply turning the stem 35 in i the valve 34 will one direction or the other, be moved toward or from its seat and in its up and down movements will be inclosed by the depending wings of the cage or barrel. It will be understood of course that upon removing the screw cap, the cage or barrel may be turned by means of the bonnet to disconnect 'it from the valve seat to permit the bonnet, cage, stemI and valve to be removed for convenient inspection of the interior of the casingor the valve seat. When y.,

it is desired to remove the valve seatfwitli the parts above described the bonnet isk ipped .by a wrench and turned clockwise until,vthrough itsthreaded connection with the cage, it is screwed down into engagement with can no longer descend, its continued motion will result in an up traveling movement at the cage, which will pull upon vand extract the valve seat from its lreceiving opening 5. This operation allows a tightly wedged the shoulder 7, whereupon, as it Loaaoac `grooves being Wider than the other, a valve seat adapted to fit Within said opening, a ca ge having spaced dependin arms forming 1ntervening ports detacha ly connected with said seat and provided with lugs, one Wider than the other, to engage the respective grooves, said lugs having a specified arrangement relative to the arms, a head having a threaded engagement with the cage, a cap fitted upon the .neck and holding the head in ap lied position, a bonnet carried by the hea and extending through the cap, the neck and head being formed with beveled surfaces and the cap with a beveled projection to fit down between and engage said surfaces, a valve stem adjustab y mounted in the bonnet and head, a valve carried by said stem, and a shoulder upon the neck to limit the downward movement of the head.

2. In a valve or cut-olf, a valve casing having inlet and exhaust ports, a partition formed with an opening, and a neck provided With vertical grooves, one of Vsaid grooves bein -Wider than the other, a valve seat adapte to t Within said opening, a cage having spaced de ending arms forming intervening ports etachably connected with said seat and provided with lugs, one Wider than 'the other, to engage the respec tive grooves, said lugs having a specified arrangement relative to the arms, a head having a threaded engagement with the cage, a cap itted upon the neck and holding the head in applied position, a valve stein adjustably mounted in the head, and a valve detachably connected with said stem.

In testimony whereof We affix our signatures in presence of two witnesses.
